how to program for reading the ASCII code of a character and vice versa in C language

#include <stdio.h>
#include <stdlib.h>


void main()
{
    char x;
 int n;

printf("\n enter a character");
scanf("%c",&x);
printf ("\n given character is  %c", x);
printf ("\n ASCII code is %d\n " , x);
printf("\n enter a ASCII code");
scanf("%d",&n);
printf ("\n ASCII code is  %d", n);
printf ("\n equivalent character is %c", n);
getch();
}

output:
 enter a charactera

 given character is  a
 ASCII code is 97

 enter a ASCII code65

 ASCII code is  65
 equivalent character is A

How to Perform Addition, Subtraction, Multiplication, Division and Modulus operation on two integers.

#include<stdio.h>

void main()

{ int a,b;

printf("\n enter two values: ");

scanf("%d %d",&a,&b);

printf("\n a + b = %d", a+b);

printf("\n a - b = %d", a-b);

printf("\n a * b = %d", a*b);

printf("\n a / b = %d", a/b);

printf("\n a modulus b = %d", a%b);

getch();

}

input:

 enter two values: 13  5

output:

 a + b = 18           

 a - b = 8

 a * b = 65

 a / b = 2

 a modulus b = 3
